Body training machine

ABSTRACT

A body training machine comprises a driving assembly; the driving assembly having: two treadles at two sides thereof for treading by user; a first driving belt being cyclically installed around the treadles and a first belt wheel of a damping wheel so that the treading forces applied to the two treadles will be transferred to the damping wheel; a driven wheel connected to a pull rod through an elastic connecting wire; a second driving belt encircling the driven wheel and a second belt wheel of the damping wheel so that the pull rod is interacted with the damping wheel. The first belt wheel and second belt wheel are at two opposite sides of the damping wheel. A fly wheel is installed between the two treadles, and the first driving belt is cyclically installed around the fly wheel and a first belt wheel of a damping wheel.

FIELD OF THE INVENTION

The present invention relates to body exercise machines, and particularly to a body training machine, wherein two belt wheels are engaged to the fly wheel and driven wheel, respectively so as to provide a balance effect to the structure without shift.

BACKGROUND OF THE INVENTION

Body training machines have become popular devices at home. Many body training machine serves to train the feet and hands of users, which has a form like a bicycle.

One kind of such machine has a fly wheel which is located on the treadles. The fly wheel is connected to a damping wheel through a driving belt for providing damping force to the feet of the user as the feet of the user tread upon the treadles so as to provide the effect of body training.

However in this kind of prior art, the driving belt is installed at one side of the damping wheel so that the force applied to the damping wheel is always at the side having the driving belt. The applied force is unbalance. For a long time, the damping wheel will shift and lose of balance so as to affect the normal operation of the body training machine.

Moreover, the prior art structure only provides the function of training the feet of the user, while the hands of the user are at not used.

Thereby there is an eager demand for improving above mentioned prior art structure so as to improve the defects in the prior art.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a body training machine, wherein two belt wheels are engaged to the fly wheel and driven wheel, respectively so as to provide a balance effect to the structure without shift.

To achieve above objects, the present invention provides a body training machine which comprises a driving assembly installed at a front end; the driving assembly having: two treadles at two sides thereof for treading by user; a first driving belt being cyclically around the treadles and a first belt wheel of a damping wheel so that the treading forces applied to the two treadles will be transferred to the damping wheel; a driven wheel connected to a pull rod through an elastic connecting wire; a second driving belt encircling the driven wheel and a second belt wheel of the damping wheel so that the pull rod is interacted with the damping wheel. The first belt wheel and second belt wheel are at two opposite side of the damping wheel. A fly wheel is installed between the two treadles; and the first driving belt is cyclically around the fly wheel and a first belt wheel of a damping wheel.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIG. 1 to 5, the body training machine 1 of the present invention is illustrated. The present invention has the following elements.

A cushion 11 is installed at one end for being seated by the user. Two sides of the cushion 11 have respective handles 12 for being held by the user to retain in balance. Two treading pads 13 are located at a lower side.

A driving assembly 20 is installed at a front end. The driving assembly 20 has the following elements.

A supporter set 21 serves for supporting other elements of the driving assembly 20.

A control panel 22 serves for providing information related to exercise, such as cycling numbers, or consumed heat capacity, etc. and for providing the function of setting damping value. The functions and controlling way are known in the prior art and thus the details will not be described herein.

Referring to FIG. 3, a fly wheel 23 has two treadles 231 at two sides thereof for treading by user. A driving belt 232 is cyclically installed around the fly wheel 23 and a belt wheel 251 of a damping wheel 25 so that the treading forces applied to the two treadles 231 will be transferred to the damping wheel 25 from the fly wheel 23 through the driving belt 232. Thus a damping force is provided to the treadles 231 so as to achieve the effect of exercising.

Referring to FIG. 4, a driven wheel 24 is connected to a pull rod 242 through an elastic connecting wire 241. In operation, the user can hole the pull rod 242 to move forwards and backwards. Another driving belt 243 encircles the driven wheel 24 and another belt wheel 252 of the damping wheel 25 so that the pull rod 242 is interacted with the damping wheel 25. Thus, in operation, a damping force is provided to the pull rod 242.

With referring to FIG. 5, the damping wheel 25 is pivotally installed to the supporter set 21. A side of the damping wheel 25 has the belt wheel 251 which is connected to the fly wheel 23 through the driving belt 232 and another side of the damping wheel 25 has a belt wheel 252 which is connected to the driven wheel 24 through the driving belt 243. Thus, the damping wheel 25 provides damping forces to the fly wheel 23 as the user make the foot exercise and provide damping forces to the driven wheel 24 as the user make hand exercise. Thus in exercise, the user is in balance state.

With referring to FIGS. 6 to 8, the operation of the present invention is illustrated. In operation, the user sits upon the cushion 11. The user can tread the treadles 231 or pull the pull rod 242, or tread the treadles 231 and pull the pulling pull rod 242 at the same time as desired. In operation, the damping wheel 25 provides damping force to the users so as to achieve the effect of exercise. Thereby when the user only treads the treadles 231, the hands of the user can hold the treading pads 13 for balance.

The belt wheel 251 and belt wheel 252 are engaged to the fly wheel 23 and driven wheel 24, respectively so as to provide a balance effect to the structure without shift.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
